To allwhom it may concern:v

Be it known that IfBi-:NJAMUI F. AU- onsrmmi a citizen of the United States', residingy at B-iillalo, inthe countyv of Erie and State of New York,l have invented certain new 'and useful Improvements inI Fluid- Mixing Devices, of which the following is a specication. y i

'This invention relates to a combined fluid mixing and controlling device.

One object is ticularly adapted for mixing combustion fluids ,embodying such characteristics that theA mixedfluid possesses ness".

Another object resides in the provision of a device for mixing fluids for compression and subsequent combustion embodying among other characteristics means whereby the amount of one fluid mixedvwith another fluid is regulated with regard to the amount therleof required for mixing with the otherl Another object is to provide a devicel adapted to mix air and gasolene or other fluids and provided with a valve'which is operable under the suction to permit of discharge of the fluids therefrom with the supply `Vof the gasolene controlled by the amount of air 'discharged from the device whereby the iluids are properly'proportioned withrelation to each other.

Another objecty resides in the provision 'of' a lliiid mixingdevice embodying such characteristics as to provide for an efficient mixing of fluids, with means rovided whereby the supply of one of thf fluids may be stopped, and by ceasing thefsupply of this particular one of` the vfluidshlcutting oil supply of the remaining fluid or tluids.

. A still further object is to provide a mixing device for eliiciently mixing -gasolenc` and air, the supply of gasolen'e for admin ture with. the air being regulated according to the discharge. of the air from` the mixing device'. f

mixing device particularly adapted for connectioirwith a pump,

tion or'` other.k engine or device including means to provide for the admixture of air according to the discharge of the fluids from $5 the device.

`With the above and other objects in view the present invention consists inthe combination .and arrangement of parts therein# v size and minor devThe rotary compressorillustratd inthe y I figure isbut one type of rotary compressor with which my improved mixingdevice may t be connected. As the compressor illustrated ressor to point 1m' roved mixing device. With this :understeiding it may co ipressor of this invention, l have illustra ed merely sutiicient structure of a com out the operation of my.`

be recited that the rotary K shown consists of a casing inclulding. a cylinder 5, an inlet chamber '6. a

compressing chamber 7 and abuse 8, the inlet and compression chambers being on op,- sides of a dividing wall 9 with the( inlet chamber 7 .provided with an outlet port 11; a' central chamber in abutment 12- which latter has an eccentrically disposed cylindrical chamber 16. The

outer face ot the abutment isvcylin rical and concentrically disposed relative t the axis of a driving shaft 13 on which 'inoiinted 14 provided with a plurality of pistons 15 which are adapted to slide radially relative thereto. 'n

`The abutment 12 engages the upper end of the vertical dividing wall 9 d completes the inlet side of the com ressor from the discharge side thereof so that the Hiihlpassing through the compressor must pass through the cylindrical chamber 16 in the abutment. Formed in the abutment at the inlet side of the compressor is a` circumferentially disposed slot 17 which communicates with one or more slots 18 on the inner side of the4 abutment by a flared said passage with. an inlet port chamber provided c Thecylinder 5 f has whichis'located n nextend preferablyl from av pointiadj'acent the vertical wall 9 to a point 2() which above the center of the drive shaft 13.

On the discharge side of the compressor connection is made with the compression chamber I by providing the abutment with la` `discharge slot 22' which is similar in con- *passage 19 connects the slots 17 and 125. l The' struction to the inlet slot or port 17. This discharge poi-t2?, consists ot' aA circumferential slot -in the outer face o'tthe abutment extending from the vertical wall Soto a point' 23 `ivliich'is above theicenter o the. cylindricaiclramber. Thel inner fa e of the abut ment at the dischargefsideoft e ompressor' is' provided with one or n'iore'slots 24 which may beA similar to the slot or slots 18 there being a flared passage 25 connecting the.

slots 22 'and inthe saine manner as the compressor creates a suction or vacuum and it will be apparent, there-'fore'. lthat the fiuid drawn inlthrough the inlet ports may be conveyed th ough the cylindrical chamber to the, dis'cli rge sports, thence to the main compression chamber. 7. From the main compression chamber the compressed fluid passes to a suitable receiver 28 or' other device, there being. aV valve mechanism A Abetween the compression chamber 7 and the receiver which is operable under the intlu-.

ence ofpressure in the compression chamber .to permit passage of the compressed fluid t'o the receiver` Vhen the fiuid in the receiver 28 reaches 'a predetermined pressure it forces the valve mechanism A. to closed position and a portion ofthe fluid passes through the conduit 29 to a' relietl valve mechanism B to operate the same to open it and permit the fluid in the compressor to circulate through the same by way of one or more ports 3.0-31 in the dividing wall 9.

As has been stated,- vtheessential feature ot' my invention in this case resides .in the fluid mixing device. which in. addition to ellil ciently mixing the fluid. also controls they supply of the 'fluid delivered to a compressor or to a coi'nbustion or other engine or device. lTo properlyv mix aii and and control the supply of saine to a compressor or the like I liaveprwided my improved de'- 1if-ice, which. in the compressor lillustrated in the accompanyingdrawing, is connected up with the casinar of the Icompressor atthe in-.

let port l0. This in'ipi'oved'flevicehas its casing 33 divided by a partition c into air and gas chambers b and c. respectively, withl a controlling valve which is preferably cone shaped and which engages a y cone' `shaped seat 32 normally closing the valve Wardly O ffthe air chamber b and at its op'- posite endengagzes a collar '37 on-the valve stem 34. This spring 35 normallyv holds the valve closed. "It is on the suction stroke of therotary piston carrier 14 of the coni-ff,I

presser which opens the valve is andv draws the` fluid into the coinp'ressor through the port 10 for compression. ,it the bottom ot' the casingis au opening),r 38 tlirough which air nia'v pass' to the inlet port 10N when the 'alvez is open.

In the aforesaid partition a is a plurality of ports 3S) which establish communication between the air and gascchambers l; and c, there `being a supply pipe 41 by means of which' pipe gasolen or other fluid may pass into said chamber c.

A. pistoh valve 42 Anori-iially closes the ports `392m the partition a.. This piston val-ve is f'oi'ined'with a plurality ot' ports 43 which may be brought into register with the ports 35.) in the partition of' T li-se' ports in the piston' valve are differently spaced relai tive vt0 the ports ff'iii the partition so that as the piston valve slides first one prt and ythen another will be opened and by varying" lthe .size off said ports I am able to gradually 'open the valve and gradually increase the supply of liquid uel.

The piston valve 42 is connected lto the 'alve stein 3l of tlie valve by the connectf inglink 4i which is 'located between nuts threaded on vthe end of the piston valve and also between nuts threaded on the end of the valve stem 34. B j adjusting these nuts the position of' thepiston valverelative'to the .valve 32.4may be adjusted.

In the rotation of the piston carrier 11i on the first part ofy the suction stroke the valves SI'and will be opened` slightly if theA piston carrie-i' is rotating slowly and 4a small amount ot' air and liquid fuel drawn in through the port 10. The air and the liquid fuel will be increased in the casing 33 and delivered to the discharge side of the compressor and compressed inthe chamber" 7 and delivered to the'i'eceiver. Upon an in'- crease of the suction ,stroke so that an increased amount of air is'drawn in, the valve which controls the liquid fuel-will be opened a little further and the proper proportion oi' 'gasolene is supplied to the air chamber to make a mixture ot' a predetermined and proper richness. The richness of the mixture may be readily varied by adjusting the couiwction 44 between the valve stemll i and the I'iistonlvalve 42.

To regulate the amount of intake of air and consequently` the amount of gasolene, the suppll of the latter being controlled by thc amoi nt oi air passing through the caskv ing i may be desired to provide the iiitali'c ot the air chamber with a Butter-fly valve l 4which governs the supply of fluid to the mixing chamber.
